BRICK-MACHINE.

SPECIFIQATIONforming part of Letters Patent No. 257,665, dated May 9,1882.

Application filed February 24, 1882. (No model.)

To all whom 'it may concern Be it known that I, JONATHAN GREAGER, a.citizen of the United States, residing at Cincinnati, in the county ofHamilton and State of Ohio, have invented certain new and usefulImprovementsin Brick-Machines, of which the following is aspecification.

My invention comprises a novel construction of bumper orjarringapparatus for uniformly loosening compressed clay in brick-machinemolds, and without destroying or impairing the symmetrical shape of theunburned bricks, as hereinafter more fully described, and pointed out inthe claims.

In the annexed drawings, Figurel is aplan of my bumper. Fig.2 is avertical section of the same, taken in the plane of one of thebearing-bars. Fig. 3 is a vertical section of the apparatus, takentransversely of the delivery-frame, a mold being shown supported on thebearing-bars. Fig. 4 is an elevation of the striker and its attachedknife. Fig. 5 is a horizontal section throughone end of the same. Figs.6 and 7 are detail views of the leveling keys or wedges. w

A Arepresent the side beams, and B B B the cross-beams, of thedelivery-frame of a brick-machine of any approved construction, saidframe being so arranged as to allow the ejected molds to travel in thedirection of the arrow seen in Fig. 1. The beams AA are cut away on top,at a a respectively, to receive the bumper, jar, or agitator, whichdevice consists of two parallel beams, O C, disposed transversely withreference to said sides A A, and secured at either end by boards D E,said boards havingat-tached to them blocks d d e c, united by rounds orhandles F F;

G are bearing-bars attached to the crossbeams of the frame, and soarranged as to allow free play beneath them of the jar or bumpingdevice.

Secured to the end beam, B, are stops H H, so arranged as to arrest themold I in a perfectly square position with reference to the bumpingapparatus, as indicated by the dotted lines in Fig. 1. The bumpertravels on rollers jj', secured to bearers J J, fastened to the sidebeams, A A.

K represents a portion of a plate secured to the press-box, and L is thestriker, having racks Z l, wherewith it is raised and lowered in theusual manner by means of pinions engaging with said racks. In ordertocause this striker to act uniformly along the entire upper face of themold, and thereby scrape all superfluous clay from off the same, saidstriker is provided with two set-screws, NN, as seen in Fig. 4. Afterthe striker has once been lowered and properly adjusted to the exactlevel of the mold, these screws or bolts are tightened up, so as tosecure this plate L immovably in position. I prefer, however, to arm thelower edgeof the striker with a readily-detachable knife, 0, that can beremoved and reground whenever it becomes dulled by constant use, or incase it should be broken. This knife is secured to the striker withscrews 0, having countersunk heads presented toward the press-box of themachine. 7

Referring to Figs. 6 and 7, P represents one of the sills of themachine, said sill being notched at p to receive avertically-aetingkeyor wedge, 1t, upon which rests one of the side beams, A. Furthermore,this sill has a seat, p, for the reception of a horizontally-acting keyor wedge, B, adapted to bear against the key R. In case the frame A A BB should be too low, the Wedge R can be driven in until the properelevation has been obtained, and then the key B is driven home. By thisarrangement the key B. will be preserved from working loose, no matterhow roughly the machine may be used.

The operation of my bumping apparatus is as follows: As the charged moldemerges from the press-box of the machine the superfluous clay isscraped off perfectly level by the knife 0 and the mold is run back onthe bearingbars Gr, either automatically or by hand, until 0 it comes incontact with the stops H H, as indicated by dotted lines in Fig. 1. Themold now stands at right angles to theframe, and the operator, graspingthe handles F F, proceeds to reciprocate the bumper, so as to cause 5 itto strike alternately the opposite ends of said mold, the blocks (1 d e0 serving to impart momentum to the apparatus and compelling it togive-a sharp quick blow that loosens the compressed clay in the mostthorough and uniform manner. Owing to the location of the stops H H, theblocks dd 0 e strike squarely against the opposite ends of the mold,thereby preventing the clay being twisted out of its proper shape orbeing enlarged and thickened at the ends and corners, which defectswould occur in case the blows were delivered obliquely against the mold.Therefore the clay when dumped out of the mold will be symmetrical inshape, with the corners perfectly sharp and square.

If desired, the bumping-faces'of the blocks at the ends of the jarringapparatus may be protected with leather or rubber or otherelasticcushions, as seen at S S in Fig. 3.

Instead of the bars G, other'snitable devices may be employed forsupporting the mold and allowing free play of the bumper.

Iclaim as my invention- 1. Abumpingapparatus reciprocating'transverselyof the delivery-frame of a brick-ma chine, and adapted to alternatelyfstrike the opposite ends of the charged molds, in com- 25 bination withsuitable stops for arresting said molds in a proper position,substantially as described.

2. .The combinatiomin a brick-machine, of

.delivery-frame'A a A a, reciprocating bump- 3o er 0 C D E, hearing-barsG, and stops H H, substantially as described.

3. A brick-machine bumper consisting of the beams O 0, ends D E, blocksd d e e, and handles F F, as and for thepurpose specified. 3 5

4. The bumper G G D d d F E e e F,- mounted on rollers j j, andreciprocating transversely of the delivery-frame of a brickmachine,substantially as herein described.

In testimony whereof I aflix my signature in 40 presence of twowitnesses.
